Özet:

 This study was conducted to determine some bioecological characteristics of Lepomis gibbosus L. 1758, commonly known as pumpkinseed sunfish, which spreads in Gökpınar Dam Lake GDL in Denizli Province. The fish samples were captured with an experimental seine net and multimesh gillnet from May 2019 to April 2020. During the samplings, certain physicochemical parameters of GDL were measured, habitat utilization, relations to environmental variables, feeding habits and interspecific interactions with other fishes of L. gibbosus individuals were observed. It is observed that GDL provides a suitable habitat for L. gibbosus in terms of water quality and other ecological requirements. A total of 1005 L. gibbosus individuals, consisting of 302 females, 605 males, and 98 juveniles, were sampled throughout the study, and biometric studies were conducted. In the population males were found to be dominant. The averages were determined as follows; total length as 5.822.09 cm 2.46-11.34, weight as 4.944.67g 0.20- 34.65, and condition factor as 1.710.24. The ages were determined between 0 to IIand Age-length relationship VBGE was estimated as L_t 19,851-e-0,2744t0,272   Spawning occurs between April and June in individuals at the age of I. It has been observed that the species exhibits good growth rates in this habitat, displays opportunistic omnivorous feeding behavior, preys on another invasive alien species, Gambusia holbrooki, present in the lake, and competes with the same species for habitat sharing. It has been determined that L. gibbosus has formed a self-sustaining population in GDL, but it utilizes a limited lake area as its habitat. In conclusion, GDL is considered as a hydrologically unstable and highly variable habitat. L. gibbosus population of GDL exhibits significant similarities in terms of bioecological characteristics with populations that spread outside its natural spreading area. As L.gibbosus is an exotic fish and might be have invasive traits, it is necessary to monitor of the population regularly, and control measures should be taken to prevent its spread to other inland water bodies.

 Bu çalışma, Denizli İli Gökpınar Baraj Gölünde GBG yayılım gösteren güneş levreği Lepomis gibbosus L. 1758un biyoekolojik özelliklerini belirlemek amacıyla yapılmıştır. Balık örnekleri Mayıs 2019-Nisan 2020 arasında deneysel ığrıp ve uzatma ağlarıyla yakalanmış, örnekleme esnasında GBGnün bazı fizikokimyasal parametreleri ölçülmüş, kaynağın kullanımı, çevresel değişkenler, bireylerin çevreyle etkileşimleri gözlemlenmiştir. GBGnün L. gibbosusun su kalitesi ve diğer ekolojik istekleri bakımından uygun bir habitat olduğu görülmektedir. Çalışmada 302 dişi, 605 erkek ve 98 jüvenil toplam 1005 adet L. gibbosus bireyi üzerinde biyometrik çalışmalar yapılmıştır. Erkeklerin baskın olduğu görülen popülasyonda, ortalama toplam boy 5,822,09cm, 2.46-11.34, ağırlık 4,944,67g 0.20- 34.65 ve kondisyon faktörü 1,710,24, yaş 0- II arasında tespit edilmiş, yaş-boy ilişkisi VBBE Lt  19.85 1e -0,274  t  0,272   olarak belirlenmiştir. Üremenin I yaşlı bireylerde Nisan-Haziran arasında gerçekleştirdiği tespit edilmiştir. Türün bu habitatta oransal olarak iyi büyüdüğü, fırsatçı omnivor beslenme gösterdiği, gölde yaşayan diğer bir istilacı yabancı tür Gambusia holbrooki yi av olarak kullandığı ve aynı türle habitat paylaşımı için rekabet ettiği görülmüştür. L. gibbosusun GBG de kendi kendini sürdürebilir bir popülasyon oluşturduğu ancak kısıtlı bir alanı habitat olarak kullanabildiği tespit edilmiştir. Sonuç olarak, L. gibbosus hidrolojik olarak kararsız ve çok değişken bir habitat olarak değerlendirilen GDL de, biyoekolojik özellikler bakımından doğal yaşama alanı dışındaki popülasyonlar ile büyük ölçüde benzerlik göstermektedir. L.gibbosus egzotik bir balık olduğundan ve istilacı özelliklere sahip olabileceğinden, popülasyonun düzenli olarak izlenmesi ve diğer iç su kaynaklarına yayılmaması için kontrol önlemlerinin alınması gerekmektedir.
